Extracellular Vesicle Properties and Functions Are Defined by the Originating Cell's Fitness Status

Journal of Extracellular Biology, Volume 5, Issue 2, February 2026.
ABSTRACT Recent studies have focused on the role of dying cells in modulating immune function and shaping the local microenvironment. Apoptotic cells release various extracellular vesicles (EVs), such as exosomes and microvesicles, and form apoptotic bodies through membrane blebbing.

Seleção genética de Biomphalaria glabrata e Biomphalaria tenagophila visando a alteração da suscetibilidade e resistência ao Schistosoma mansoni Genetic selection of Biomphalaria glabrata and Biomphalaria tenagophila seeking the alteration of the susceptibility and resistance to the Schistosoma mansoni

Revista da Sociedade Brasileira de Medicina Tropical, 2005
Gerações de Biomphalaria glabrata e Biomphalaria tenagophila selecionadas geneticamente para resistência e suscetibilidade ao Schistosoma mansoni das linhagens BH e SJ foram utilizadas no estudo da adaptação do trematódeo ao hospedeiro intermediário.

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Population Ecology, Volume 68, Issue 1, January 2026.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

ITS2 variability of Biomphalaria (Mollusca, Planorbidae) species from the Paranapanema Valley (São Paulo State, Brazil): diversity patterns, population structure, and phylogenetic relationships

Genetics and Molecular Biology, 2007
The ribosomal DNA internal transcribed spacer 2 (ITS2) has been shown to be a useful genetic marker for species identification and phylogenetic reconstruction in the genus of freshwater snails Biomphalaria (Preston 1910).

Habitat Structure Shapes Mollusc Assemblages in an Urban Semiarid River: Implications for Conservation and Public Health

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT Fine‐scale environmental drivers shape freshwater mollusc assemblages in urban semiarid rivers. We examined how substrate composition and water chemistry influence mollusc richness and abundance along a polluted stretch of a river in the Brazilian semiarid region. Surveys at five sites recorded 2479 individuals.

Longitudinal survey on the distribution of Biomphalaria sudanica and B. choanomophala in Mwanza region, on the shores of Lake Victoria, Tanzania: implications for schistosomiasis transmission and control

Parasites & Vectors, 2017
Background Schistosomiasis is hyper-endemic in the Lake Victoria basin; with intestinal schistosomiasis plaguing communities adjacent to the lake, where the intermediate host snails live.

Biomphalaria glabrata immunity: Post-genome advances

Developmental & Comparative Immunology, 2020
The freshwater snail, Biomphalaria glabrata, is an important intermediate host in the life cycle for the human parasite Schistosoma mansoni, the causative agent of schistosomiasis. Current treatment and prevention strategies have not led to a significant decrease in disease transmission. However, the genome of B.

Taxonomic Deception via Obvious Traits: Oversplitting in European Vallonia Risso, 1826 (Mollusca: Gastropoda: Valloniidae)

Zoologica Scripta, Volume 55, Issue 1, Page 37-51, January 2026.
ABSTRACT The status of the six traditionally recognised European Vallonia taxa is considered based on mtDNA and nDNA sequences from five independently sorting loci in combination with morphometric landmark analyses conducted on genetically confirmed shells. These analyses document that only two species are valid (V. costata and V.

Genetic Diversity and Ecological Distribution of Bulinus Populations in Southern Benin Using PCR‐RFLP Analysis

BioMed Research International, Volume 2026, Issue 1, 2026.
Schistosomiasis remains a major public health concern in Benin. Freshwater snails of the genus Bulinus serve as intermediate hosts for schistosomes, trematode parasites responsible for bilharzia. The urinary form, caused by Schistosoma haematobium, is the most prevalent and is primarily transmitted by Bulinus truncatus and Bulinus globosus, whereas the
